The mailing list for listmasters using Sympa

[address@concealed]

Can we use this to handle "Private post" if users have and send email to the
list from mutiple mailboxes?

We have a few users who have mutiple mailboxes, but only their primary 
addreess
(or registered) was added to lists. Their lists were configured as private 
post
(only list members can post).  However, they want to post to the list from all
their mailboxes (some of them have a crontab sending email out).  I was trying
to figure out if this can be done with "Your other email address".  
An account was created for me with my secondary email address to be the
username.  I added my primary email address to this account as going through
"Preferences" and "Your other email address", saw both email addresses under
"your other email addresses".

I was trying to send a test mail to one of the lists which has my primary
address but Sympa still forwards this to the moderator.  In addition, the
information is not retained after I logged off and logged back in.  I went to
Preferences -> Your other email addresses but I do not see my primary and
secondary there.

Should the information be retained and should Sympa treate the post from the
secondary email address as the primary one?

Can someone help?

Thanks in advance guys!
